although this wasn't the original problem, i like it, too :).  but now
i am stuck in finding an optimal implementation for lines.
Isn't the obvious one good enough?
lines [] = []
lines s = go s
  where
    go [] = [[]]
    go ('\n':s) = [] : lines s
    go (c:s) = let (l:ls) = go s in (c:l):ls
thanks.  good enough, yes.  just not obvious to me...  (-:
